Is it possible to see in Axon PBX how long an extension talked on a monthly basis? Does Axon have an option to generate reports?

Axon provides a ".csv" file with all phone calls made. Fields include Date, Time, From, To and Duration. Axon also keeps System Logs which has more detailed system messages and progress in text form.

You can also export the details in this text file to any tool you wants to use to generate a report. You can push the data to CSV, ODBC, or even to a web service and then use your favorite data browser to mine the info. We do not provide support for the programming portion, you will need to manage it yourself.
